AI Technical Summary
⚠Technical Problem
In existing flue gas denitrification devices, the ammonia water is not fully mixed with the flue gas when the flue gas velocity changes, resulting in poor denitrification effect.
⚗Method used
The inverted U-shaped reaction shell design, combined with the atomizing spray mechanism and exhaust unit, ensures effective mixing of ammonia water and flue gas by changing the flue gas rate and uniformly delivering the mixed gas.
🎯Benefits of technology
This improved the mixing efficiency of flue gas and ammonia water, ensuring the stability and high efficiency of denitrification.

Abstract
The utility model relates to a flue gas denitration device, including air inlet casing, reaction casing, exhaust casing, air inlet casing outside is equipped with atomization pump, inside is equipped with with atomization pump connects atomization spraying mechanism, reaction casing is inverted U shape, one side is connected with air inlet casing top, the other side is connected with exhaust casing top, the inside of vertical section of reaction casing is equipped with exhaust unit in air inlet casing one side, exhaust unit is used for changing the flue gas rate in the reaction casing, the inside of vertical section of reaction casing is equipped with deamination reactor in exhaust casing one side, the inside of horizontal section of reaction casing is equipped with gas delivery unit, exhaust unit includes fixed base, exhaust pipe, connecting pipe, connecting seat, spring, exhaust hole. The utility model can change the flue gas rate in the reaction casing, and then can avoid the problem that the flue gas cannot be mixed fully and makes the denitration effect poor because of entering the reaction casing too fast.
